Sure you can plot a persons color vision defect with this tool.... but to
think that you could get a group of people to eat or drink something like
chocolate or coffee with sugar then see the results using this test is a
bit of a stretch.
I attempted this (with the Farnsworth-Munsell Hue test) some years ago and
after hours of research (reading and interviewing color scientists) and
running groups with sugar and placebos, I came to the conclusion that
there are too many factors to test using this tool to validate the
hypothesis that sugar will change your color vision. My sense is there are
other tests that are more closely tied to the medical community for testing
color vision defects.
Three conclusions I have come to is that the Farnsworth-Munsell Hue is
(1) really just good for describing how a person sees color (on a plotted
graph) and (2) how consistent a person is at describing color. And (3) using
the results as a long term benchmark.
